[QUOTE="gunz4me2, post: 7119944, member: 613729"] Quality amplifiers do not have as much of a sound difference as others are lead to believe. I've performed an experiment many times with amplifiers set up in the home powering some Klipsch HT speakers and none of my friends could tell the difference between a Cerwin Vega EXL 400.4, Soundstream Reference 700s, RF Power 351s, and several other amplifiers I owned. I limited the power output to 10 watts RMS per amplifier and faded front to rear on my test bench HU to switch the amplifiers out. I even level matched the output from a TIPS modified Linear Power 1502IQ and compared it to an unmodified 1502IQ with one amplifier on the left speaker and one amplifier on the right speaker. I couldn't tell a difference and no one else could either! That was my lesson learned in psychoacoustics. If the amplifiers measure relatively close over their useful frequency reproduction range and produce relatively close amounts of clean, distortion/noise free, power, one will be hard pressed to tell the difference between two amplifiers. This goes double for an amplifier that is installed in the worst possible environment for audio reproduction, the automobile itself! The only hard part is finding those budget diamonds in the rough that give you the clean, distortion and noise free power! [/QUOTE]
